If in-lining is that big a concern, you could create your own wrapper function and explicitly mark it no-inline. Personally, I haven't seen any inordinate increase in i-cache miss rates because of in-lining on the applications we have - prefetchers on IA are usually capable of keeping up. However, every application is different enough that there really is no "general" rule here.

We use link-time-optimization without any problem.
No big performance gain, but I really don't think all the inlining of big functions is necessary.
